A Case of Synchronous Mucinous Tumor of the Ovary and Appendix / 대한산부인과학회잡지

ABSTRACT

The coexistence of mucinous ovarian and appendiceal tumors in associated with pseudomyxoma peritonei is well established. But, ovarian and appendiceal mucinous tumors occur without involvement of other organs is unusual. When the two lesions are morphologically similar, it is difficult to determine whether one reflects a metastasis or whether the tumors are independent. The typical synchronous presentation of the ovarian and appendiceal tumors, their histologic similarity, the frequency of bilaterality of the ovarian tumors, the predominance of right-sided ovarian involvement. Adenocarcinoma of the appendix constitutes 0.2 to 0.5 percent of all gastrointestinal tumors and accounts for 6 percent of primary malignant lesion of the appendix. The authors experienced a rare case of synchronous tumor of ovary and appendix in 59 years old female patient who has suffered for 3-4 months from abdominal pain. Pathologic examination of the resected specimen revealed a synchronous mucinous type tumor of vermiform appendix and ovary.
